Abstract
Energy-dependent global Dirac optical model potentials are found by fitting proton elastic scattering data in the energy range 20–1040 MeV for , , , , and . Three different energy- and atomic-mass-number-dependent global Dirac optical potentials are also obtained. A number of characteristic features of the potentials are discussed. In addition, the mean free path, the effective mass , the Dirac mass , and the relativistic energy shift are calculated.
